My invention relates particularly t0 apparatus of the character set forth in my Patent #1,717,091. A

One of the important advantages of that construction is the facility with which apparatus may be installed which installation in A and contacts are likely tobe covered with dirt and in fact the cable opening is quite large and admits dirt to the outlet box behind the wall plate. ,To avoid these difficulties I propose to provide a protecting housing adapted to be readily attached to the support to cover the conductor opening, the terminals and the contacts While plastering and other. work is being completed. I have also sought to simplify and perfect the terminal and contact construction and the method of supporting and insulating the same.

Fig. 1 is a front view of a terminal Wall plate with its wiring protector and showing an outletbox dotte Fig. 2 is a vertical sectional view.

Fig. 3 is a front view showing the circuit terminals without the protector.

' Fig. 4 is a vertical section of a modification. V

Figs. 5 and 6 are perspective views of devices for attaching the protector to the terminal sockets.

The wall plate 10 has an insulating block 11 attachedto it by rivets 12.

This block 11 carries a series of terminal and contact members arranged in a row as shown in Fig. 3. Each Unit consists of a terminal plate 14, jaw contacts 15 and 16 and one or more connecting fet 17 connected by .rivet 18 to the terminal plate 14 and pro vided with a binding screw 19. The feet of the jaw contacts 15 and 16 are located in a groove in the rear of the block 11 and the jaws themselves pass forwtrdly through openings 20 arranged adjacent the respective binding screws. The plates14 and screws 19 are also .ammmws v 7 19:30. rial 1%. 462,265.

pr'eferabl Set" into rcesses 21 t0 assist in positi0ning them and also to assist in rtaining'the nds ofthe cond'uctdrS 22. The plate 10 is preferably providd with an oPening 23 extending along the upper edge of the block 11 and th1*ugh Which the various conductors afre passed; The upper edge of the block 11 is proVided withinclinedportions 24 leading to the terminal plates so that the respective conductbrs are spaced apart by ribs 25.

' Alayr of irisulating'material 26 is also preferably provided interPosfed betweer1the Ickof'the block 11 and the face of the plate 10- to insulate the rear of the feet 17 from the plate; This method of construction is very economical-and results in a-reliable and stand ardized construction capable of connection in many Ways to constitute vari0us circuit re' Uirements.

' nFig. land Fig. 2 I'haVe indicated an outlt'b0X30tdWhich the vvall plate 10 isse-.

crd' by' a number of screws 31 in thecus tomary manner; the wallplate beirig' pro vided Wifih a nu1ribrof slots such as 32 to permit -the jattachnuerit of "the plate todifi'erent siz S 'and'shaPes of outlet boxes and also to plate permit.angular adjustment of the Wall* forpurposes; of alignn1ent.

It-Will bendert0od' that the parts thus' fardscbd Will be or'dinarily instlalled in a; building during the procesS of construction and the wiring"completed, thus lea vingf the wire ends' a'nd the terminal plates and plug contact sockets'exposed. jTo temporarily prbtect the parts during completion of the construction andhuntil the other parts of1the telephone instrument are ready for installation," I provide a protector member 35=Whichis in the form ofa steel case havihg opexihg2and interlocked behind the upper edge 37. The loWer edge of the case 35 is provided with a spring tongue 38 adapted to' pass through the slot 39 in the wall plate so. asto provide a. frictional latching engagement.

The case 35 is large enough tocover the en. r

have a flange or flanges such as 40 to extend outward far enough to cover some of. the slots such as 41 which have been provided for the attaching screws. The principal protection 5 required, however, is for the contact jaws, the terminal connections and the opening through which the conductors extend.

Instead of connecting the protector directly to the Wall plate 10, I may employ one or more plates such as 43 secured to the case and adapted to be inserted into corresponding contact jaw sockets as shown in Fig. 4. Instead of using a number of small plugs in plates 43 as shown in Fig. 5, I may emplo;

.15 a single strip 44 as shown in Fig. 6, which isadapted to engage in a number of the contact sockets to provide the necessary -frictional engagement to support the protector in this covering position. r

I claim: v

1. A telephone wall plate with circuit terminals and plug-in contacts and a detachable protector cover having means for securing it to the wall plate.

2. A telephone support comprising a wall plate having an opening for conductors, an insulating block mounted in the front of the plate and having terminals and connected' contact jaws and a protector for the conductor terminals and aws having means for detachably securing it to said support on said opening. V 1 p:

3. A terminal support for telephonescorn prising a Wall plate, an insulating block hav- '35 ing a passage thtough it with a groove in the rear, a contact jaw extending through said passage and having a foot insaid groove, a terminal plate on the front of the block adjacent said jaw, a rivet securng the plate 40 and foot to the block a binding screw adjust-- able in said plate and means for securing said block on said wall plate. r

4. A telephone installation comprising a wall plate having openings and a series of terminal plates and contacts and a protector casing for enclosing the plates and contacts and having fingers adapted to pass through the openings to hold the casing in place.

5. A telephone installation comprising a wall plate having a conductor opening and a series of terminal plates and contacts adjacent thereto,a protector casing and means for detachably securing the protector casing' in place, covering said conductor opening and the terminal plates andcontacts.
